## Homework Statement

Assuming a pendulum to behave like a quantum oscillator, what are the energy differences between the quantum states of a pendulum of length 1m? Are such differences observable?

## Homework Equations

## The Attempt at a Solution

would the energy differences just be 1 since for each energy state n you have E_n=(n+1/2)h_bar*sqrt(k/m)? This would not be observable either since these are such low energies... correct?
